Abstract
1. Устройство квантования, которое выполняет многоступенчатое квантование с использованием поиска по дереву, содержащее:секцию поиска, которая сопоставляет каждую из одной или более целей кодирования с кодовым вектором, хранящимся в кодовой книге, чтобы выбрать некоторое число кандидатов, включающих в себя кандидатов в порядке от меньшего искажения квантования, при этом число кандидатов определяется на предыдущей ступени или определяется заранее;секцию вычисления, которая вычисляет вектор ошибки квантования путем вычитания кодового вектора из целевого для каждого из кандидатов; исекцию определения числа кандидатов, которая определяет некоторое число кандидатов, которое должно быть использовано на последующей ступени, на основании числа кандидатов, определенного на предыдущей ступени.2. Устройство квантования по п. 1, в котором секция определения числа кандидатов определяет число кандидатов, которое должно быть использовано на последующей ступени, путем уменьшения на один числа кандидатов, определенного на предыдущей ступени.3. Устройство квантования по п. 1, в котором, в случае, когда число кандидатов, определенное на предыдущей ступени, не больше заранее заданного значения P, секция определения числа кандидатов определяет, что если значение искажения квантования больше предварительно определенного порогового значения, значение P используется в качестве числа кандидатов на последующей ступени, и определяет, что если значение искажения квантования не больше предварительно определенного порогового значения, значение Q, меньшее, чем заранее заданное значение P, используется в качестве числа кандидато1. A quantization device that performs multi-stage quantization using a tree search, comprising: a search section that matches each of one or more encoding goals with a code vector stored in the codebook to select a number of candidates including candidates in order from less quantization distortion, while the number of candidates is determined at the previous stage or determined in advance; a calculation section that calculates the quantization error vector by subtracting the code of the projector of the target for each of the candidates; a section for determining the number of candidates, which determines a certain number of candidates to be used in the next step, based on the number of candidates determined in the previous step. 2. The quantization device according to claim 1, wherein the section for determining the number of candidates determines the number of candidates to be used in the next step by decreasing by one the number of candidates determined in the previous step. The quantization device according to claim 1, wherein, in the case where the number of candidates determined in the previous step is not greater than a predetermined value P, the candidate number determining section determines that if the quantization distortion value is greater than a predetermined threshold value, the P value is used in as the number of candidates in the next step, and determines that if the quantization distortion value is not greater than a predetermined threshold value, a Q value less than a predetermined value P is used uses as a candidate number
